    Can an observer specifically define the position a particle or is it a matter of equal probability whether the observer defines either the particle's position or motion?

    Not so clear to me what it is you are asking. Could you elaborate, provide some context, perhaps ?

    And -- a belated -- welcome to PF :smile: !

    Some measuring devices and techniques determine position and others determine momentum. We get to choose which one we use.
